<p>I keep getting this:<br>

<div class="message_inline_image"><a href="/user_uploads/4715/UYfv-Voh568SnXsYaZsHt6AS/image.png" title="image.png"><img src="/user_uploads/4715/UYfv-Voh568SnXsYaZsHt6AS/image.png"></a></div><p>Is there some setup I need to do before trying that link on the perf results?</p>

<p>some of the processed links don’t work yet on perf.rlo: there are two versions of the self profile file format and we haven’t yet been able to complete the work to handle both — currently, only the links on the runs using the older format will work, the newer format will cause this error when downloaded. (I’d like to try to reverse this soon until we can complete that work — so that the recent runs don’t cause errors while the older do — and see if we can hide the links when they would fail, etc.) so it’s not your fault at all. if you really need to use the FF profiler for a run: you could download the raw profile, use the measureme tools to process it, and upload that to the profiler site</p>
